Get journey enrollment

Read one enrollment with its step history (each node taken, outcome and time) and the sends it intended: each send node took an eligibility reservation (status intended) or records why it could not (blocked, deferred, failed). Each intended send is delivered through Nexus email.send when the workspace has a verified sender (sending_settings.get), queued in the outbox when no Nexus credential is usable, and only recorded when no sender is configured.

Outcome

Before you start

Verify identity and pin the intended organization and environment before discovering the action.
Discover a granted Nurture workspace. The application permission is workspace:read; required workspace access is read. A permission alone does not supply a workspace grant.
Organization and workspace come from verified context. Select resourceType/resourceId separately from action input; body fields cannot grant a different organization or workspace. The first authorized product action can initialize an identity-only workspace mirror.

Discover the target

topolo whoami --json
topolo actions get app_topolo_nurture.journeys.enrollments.get --detail --json
topolo resources topolo-nurture --json
topolo workspaces list topolo-nurture --json
topolo actions get app_topolo_nurture.journeys.enrollments.list --detail --json

id: Journey enrollment id, not a journey id.

Request

GET /api/journey-enrollments/{id}

Save action input as payload.json. The reviewed plan separates path identifiers, query fields and HTTP body. Set NURTURE_WORKSPACE_ID from granted resource discovery; it is separate from action input.

Inspect and test this action in the signed action console. A test response still requires the verification below.

Input fields

Field	Required	Type	Constraints
`id`	Required	string	Journey enrollment id, not a journey id. {"minLength":1,"maxLength":64}

Exact input schema:

  },
  "required": [

}

Effects

Reads one enrollment, its steps and intended sends without changing state.

Interpret the response

The returned identifier path is $.enrollment.id for journey_enrollment. Empty lists do not discover a target.

Confirm steps[].seq is strictly increasing.

Worked examples

Actual dispatcher and migration-created SQLite or Worker handlers; identity/workspace and external service dependencies are simulated. Fixture identifiers and timestamps are synthetic. These responses establish no live authorization, paid generation, credential provisioning or message delivery. Replace synthetic identifiers using credential-scoped discovery. A local success is not evidence of a deployed effect, configured provider or delivered message.

Successful request

Actual dispatcher and migration-created SQLite; verified identity/workspace and external CRM, Engage, Notify, Consent, Nexus, Brand, Generator, Voice and delivery dependencies are simulated. No live authorization, paid generation or external delivery is established.
